Another of my tests involved creating a 2 disk mirror and a 2 disk 
stripe, copying 100 gigs of data to the mirror, then copying from there 
to the stripe.  This test was successful as well.

A bit more info on the system that i realize i left out:
These tests have been run on 6.1-RELEASE and 6.1-STABLE (which is what 
im currently running), updated as of June 25th).
The hardware is an AsRock K7VT4A Pro motherboard with an Athlon XP 
Mobile 1900+.  512 megs of ddr ram, only add-on cards are the SIIG card 
i mentioned previously and an old AGP video card.
